SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 447,404, dated March 3,1891.

Application filed March 26, 1890.

To (LZZ whom it may concern.-

Be it known that I, ISAAC GILES, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Improvement in Sash-Fasteners, of whichthe following is a specification.

My invention has relation to sash-fasteners, and more particularly tothat class thereof which, while used for locking both sash when in theirclosed position, is also adapted to permit of the upper sash beinglowered and of the lower sash being raised to any desired position andlock both the sash in their ad- 'justed position; and the invention hasfor its principal objects, first, to provide I a sashfastener of theclass described, in which the locking-bolt is operated to lock or unlockthe sash by means of a bolt or spindle, which is adapted to be screwedinto or out of a housing or casing secured to the top rail of the lowersash, as hereinafter fully described; secondly, to provide asash-fastener of the class described in which the belt-operating spindleis provided with a detachable head, whereby the latter may be removedafter the sash have been looked, and thus prevent any unlawful unlockingof said sash; thirdly, to provide a sash-fastener of the classdescribed, in which means are supplied for giving an audible signal whenthe sash are being unlocked.

With the above objects in View my invention consists in theconstruction, arrangement, and combination of parts, all as hereinafterfully described, illustrated in the drawings, and pointed out in theclaims.

In the drawings, wherein similar letters of reference indicate likeparts on each figure, Figure l is a perspective View of my improvedsash-fastener, showing the detachable head for the operating-spindleremoved therefrom.

Fig. 2 is a front elevation of the Same, showing the locking plate orcatch engaging the operating-spindle to prevent turning of the same.Fig. 3 is a vertical longitudinal section, partly in elevation, of mydevice, and Fig. 3 is a detail perspective view of one of the plateswhich are secured to the upper sash and are adapted to receive the endof the locking-bolt. Fig. etis a detail perspective View of thelocking-bolt and a port-ion of Serial No. 345,405. (No model.)

its operating-spindle. Fig. 5 is a like View of the locking-bolt. Fig. 6is an elevation of a portion of the upper andlower sash, showing themanner of applying my improved fastener. Fig. 7 is a verticallongitudinal section, slightly enlarged, of my sash-fastener, showing adifferent arrangement of the signaling device.

In the construction of my improved sashfastener I employ a housing orcasing A, which may be of any suitable construction and have any desiredconfiguration. In the drawings I have shown the same as beingrectangular of form and as consisting of the sides a a, the top a, andthe end wall a a The housing or casing is left open at the bottom topermit of the assembling of the internal parts of the device, and thesides a care provided with perforated cars a to adapt the housing to besecured to the top rail of the lower sash at any point where it willmeet the rail of the upper sash, or at one side thereof, as shown inFig. 6, so as to be opposite the side rail of the upper sash. The frontwall a of the housing is provided with a central threaded perforation bfor the reception of the threaded bolt-operating spindle B, which latteris adapted to be screwed into and out of the housing through said frontwall, and thereby operate the locking-bolt, as will presently appear. Inorder to facilitate the turning of the spindle, I provide the same atits forward end with a milled head B. The rear end of the spindle whichlies within the housing is reduced in diameter, as at b, and has theenlarged portion 17 in rear of said portion 1;.

C indicates the boltby means of which the two sash are to be locked intheir closed or partially open positions. Said bolt I have shown ashaving the rectangular portion or head 0' conforming to theconfiguration of the interior of the housing within which the bolt isfitted and adapted for longitudinal movement. The bolt also has thereduced cylindrical shank 0 which passes through a like shaped openingcin the rear wall of the housing. The head 0 of the bolt is provided withthe vertical recess 0 and a like recess 0 at right angles, thereto. Therecess C receives the reduced portion Z) of said I spindle, the mode offitting these parts together being clearly shown in Figs. 3 and 4.

For the purpose of supporting and guiding the bolt in its longitudinalmovements, the housing is provided with a longitudinal wire or rodforming a track 0', secured at its ends to the ends of said housing,while the head of the bolt is provided with a groove 0 within which liesthe wire 0. By this arrangement and construction of the bolt and spindleit will be seen that when the latter is turned to the right it will becaused to advance within the casing, and thereby cause the bolt to bemoved rearwardly and project the shank thereof beyond the housing andenter a suitable recess or depression in the side rail of the uppersash, thereby locking the two sash together. By turning the spindle tothe left the bolt will be withdrawn partially within the housing to freethe shank of the bolt from the depression in said upper sash, to freethe same and allow it to be lowered or the lower sash raised any desireddistance.

In order that either or both of the sash may be locked at differentelevations or positions the middle or side rail, as the case may be, ofthe upper sash is provided with a number of depressions or recesses,before mentioned, said depressions being located at suitable dis tancesapart.

Instead of forming the depressions within the side rail of the uppersash, which might tend to impair the appearance of the window, Ipreferably employ metallic plates D, having openings D adapted for thereception of the end of the bolt, said plates being screwed or otherwisesuitably secured to a rail of the upper sash, as shown in Fig. (5.

In order to provide means whereby the turning of the spindle to causethe unlocking of the sash may be prevented until desired, I make themilled head of the spindle detachable, as shown in Fig. 1, whereby itmay be removed from the spindle after the latter has been manipulated toeffect the locking of the sash.

The detachability of the head may be effect-ed, for instance,- bysquaring the outer end of the spindle, as at d, and providing the headwith arectangular opening (1, within which fits loosely the said squaredend (1'. The head may be attached to a chain or cord (1 secured to thehousing to obviate the liability of its being lost when detached.

For the purpose of locking the spindle against rotation when it has beenscrewed within the casing to effect the locking of the sash, I provide aspring-actuated catch or lever E, pivoted to the front wall of thehousing and having a recess 6, which is adapted to take over the squaredportion d or (Z of the spindle, as shown in Figs. 2 and t.

In order that an audible signal may be given togive warning that thefastener is be in g tampered with, an y suitable arrangement ofsignaling device may be provided, said device being located either uponthe outside of the housing or within the same. In either arrangement thesignaling device is to be operated only when the spindle is beingscrewed outwardlyto effect the unlocking of the sash. In Fig. 1 I haveshown a gong as being located upon the outside of the housing, while aclapper-arm (which may be spring-actuated or made of spring metal)extends through an opening in the side of the housing, its inner endlying within the path of the head of the bolt, so that when the latteris being pushed rearwardly within the casing the end of the arm restsupon the head of the bolt in front of the recess O fland when said boltis being retracted within the casing the end of the arm will spring overthe edge of the recess, and thereby cause its outer en d to strike thegong. In Fig. '7 I have shown the gong located upon the inside of thehousing, and in this instance I show an angular lever c, pivoted uponthe inside of the housing, one end lying within the path of the head ofthe bolt. A leaf-spring c is employed, secured at one end to the top ofthe housing,- while its other end bears upon the lever. The sides of thehousing are here perforated to render the alarm more audible.

Of course it will be understood that instead of the describedconstruction and arrangement of such signaling device any otherpreferred construction and arrangement may be employed. It will also beunderstood that various modifications in the construction andarrangement of the other details of my fastener may be made withoutdeparting from the essential features thereof.

Having now fully described my invention and the manner of its operation,what I claim, and desire to secure by Letters Patent of the UnitedStates of America, is-

1. In asash-fastener, the combination, with a suitable housing orcasing, of a locking-bolt contained within said casing and adapted to beprojected through one end thereof, and an operating-spindle for saidbolt loosely connected with said bolt and adapted to be screwed throughthe other end of the housing and thereby move the locking-bolt, and adetachable head for said operating-spindle, havinga circular bore fromwhich extends a quadrangular key-slot adapted to engage a squaredprojection on the end of said spindle, for the purpose specified.

2. In a sash-fastener, the combination, with a suitable housing orcasing, of a locking-bolt adapted to be moved longitudinally therein,and a signaling device carried by said housing or casing adapted to beoperated by the bolt when thesame is moved in one direction, asdescribed.

3. In a sash-fastener, the combination, with the housing or casing, ofthe locking-bolt located therein and adapted to be projected through oneend of said housing, said bolt being provided with the intersectingrecesses IIO described, and the threaded operating-spindle adapted to bescrewed into and out of the casingthrough the other end thereof, and

having the reduced portion passing through one of the recesses in thebolt and the enlarged portion in rear of said reduced portion fittingwithin the other recess of the bolt, all combined and operatingsubstantially as described, for the purpose specified.

4. In a sashfastener, the combination, with the housing or casing, of a1ocking-bolt con tained within said casing and adapted to be projectedthrough one end thereof, and an operating-spindle for said bolt looselyconnected with the same and adapted to be screwed through the other endof the casing, and a lockingcatch secured to the outside of the casingand adapted to engage a squared portion of the spindle to prevent itsrotation, as described.

5. In a sash-fastener of the character described, the combination, witha suitable lock in g-bolt and its operating-spindle and disk, of

an attached gong, one end of the clapper of said gong extending over thebolt or its actuating-spindle and adapted to engage a projection thereonwhen the same is withdrawn, thereby striking an alarm, as and for thepurpose intended, substantially as described.

6. In a sash-fastener of the character described, having projec-tiblebolt 0 the operating screw-threaded spindle B, provided with detachablehead, said spindle having quadrangular recess (Z near its end, incombination with spring-controlled recessed catch E, supplied with lowersquared notch e, adapted to mesh with the quadrangular recess d of saidspindle and maintain it in locked position, as setforth, as and for thepurpose intended, substantially as described.
